Is that just a normal com port? Or you talking something else? If i can help , let me know. Just give me very clear instructions. I maybe able to get another dvp from my friend , if any trial and error needs to be tested.
[Venue Pro Windows Phone 7 Development] heineken78:
I have ordered such a dongle wait time for 2 days.

You can find via google "UART to COM" adapter or "UART to USB". Or make it by yourself, schematics are everywhere in net.

Such idea to connect to uart on diagnostic port of dvp on motherboard is possible that uart is not locked and its made for diagnostics. USB uart (from usb cable) is not native an can be locked by ftm mode..

UART mode download is supported by tool!

there are.

UART pins are 11,12 and possible 1,2 touch pins on picture.

I will have two used DVPs with cracked screens and bad keybaords.. soon. So I would be willing to risk bricking them if you need a guinea pig :)
[Venue Pro Windows Phone 7 Development] unubtanium:
If needed by any dev, i have a DVP that has a cracked screen and the touch controller do not work! but it boots up and works.

So of anyone wants it for testing let me know on PM!

AGAIN: cracked screen AND touch CONTROLLER do not work(meaning that it will not register touch even with a new screen, have tried)

(are only offering the phone, NO battery and so on)

:D
[Venue Pro Windows Phone 7 Development] Nokser:
You test connect this 2 PIN's?

In tsunagi device we have exam. method to unbrick device.
[Venue Pro Windows Phone 7 Development] cdgoin:
If your talking to me.. I'll test whatever you want me to from my end. I do not have any fancy equipment though. I do know how to tear down a DVP though, as I have replaced the screen on a few already.
[Venue Pro Windows Phone 7 Development] heineken78:
I havent tested, I know that all of 4 pins or 2 of them are UART.

Also Tool given to us has option UART that can be enabled in config file.

I know also another thing,if flash will be erased 100% device will be recognised as BSP device, and tool must work.

Can you explain this methode more detailed?

[Venue Pro Windows Phone 7 Development] heineken78:
Nokser, DVP doesnt support Sd-card ever as for flashing. Thats also locked from anything via usb and pressing keys for mode switching.

Only hope is to a) activate jtag port, by finding proper pins on cpu side(i have opened it) or like in Xperia x10i to find proper qisda command for jtag to halt processor; b) use uart as native factory download mode for dvp (if its not locked ); c) Last hope release power from flashstore and try to boot processor without flash to see if it switches to download mode.

Im consulting with many specialists around, really have something to try!

Brick on DELL Logo is more than ****ty, device is working 100% and protected but apps bootloader looping on command "SPIN FOREWER".

61 a

also still have to try other 2 pins.

To be continued..

What to you need for connection to uart:

1) DVP tools (modify ini files for UART download)

2) COM port or USB (usb shematics not included)

3) UART adaptor. Here variant for COM needs VCC +5v!

with chip max232, need converter to VCC 3v. After all TX and RX, ground and vcc +3 should be connected to pins 11,12,10,1 on DVP as I showed before. Adaptor should be connected to com and powered Vcc +5vfrom usb for example
[Venue Pro Windows Phone 7 Development] maxrfon:
Do only I smell something bad here?

Well, first of all i wonder what is the OP trying to do:

Opened the post - 7.8 ROM for DVP having NO DVP at all, claiming to do something very soon having no hacking experience, searching for Bootloader unlock having no clue what it is, etc etc....

Asked a phone and (or) donation to buy some. . . . So for me it clearly seems like a scam.
[Venue Pro Windows Phone 7 Development] Dajinn:
lol
[Venue Pro Windows Phone 7 Development] fubag:
dead on maxrfon!
[Venue Pro Windows Phone 7 Development] SirMcFrosty:
whatever maxrfon but i see a progress in development for our beloved dvp ;) and that i havent seen since the dvp came on the german market.

so instead of blablabla try to help ;) so u can protect us against providing a scammer with more donations :) (did anybody donate? did he ever request a donation? no i dont think so) :p
[Venue Pro Windows Phone 7 Development] heineken78:
Partically agree with Max..

But disagree with - he has no solution yet :)
[Venue Pro Windows Phone 7 Development] Nokser:
I forgot, you're a great dev ;)

Now I suspend work on dell venue pro.

I did not take any donations that I owed ​​nothing.

Have Fun!

Nokser :)
[Venue Pro Windows Phone 7 Development] fubag:
Instead of toying with the idea that we can port a custom 7.8 ROM on this baby, can we just close this thread (and be realistic) so we get some peace?
[Venue Pro Windows Phone 7 Development] kid1988:
did he just say that he quit? or did I read wrong?

not sure if maxrfon read the entire thread..

I agree the opening post (as the entire topic) is a bit confusing, especially for a "noob" like me.

and somebody did donate a DVP

but I have a feeling there is some progress. I think it's vital for a developer community to allow speculation and reach out to each other, especially in early stages of development.

I know XDA these days is more or less a collection of individual beta or final roms by devs that contact each other by PM and some do not even allow the use of their products (which may be fair but is not my point).

But there should be some room for public discussion in early stages of development, of course when not conflicting with the board rules.

I am sorry I am not able to contribute anything useful to this topic since I have no access to specific diagnostics hardware or the required knowledge.

Anyways, I follow this thread like a dog watching tennis.
[Venue Pro Windows Phone 7 Development] heineken78:
Seems like thread woke up =)

Here is schematics of uart 3.3v for DVP factory tool owners. Going to assembly this weekend.

As I wrote before I had a little success to communicate with device via this tool, but due voltage difference on adaptor (5v chip instead 3v chip, while pc com port works with 12v) wasnt possible to connect -my made adator 5v from yesturday is burned during modification.

Such a adaptor(uart 3v) was built in cables of old siemens smartphones, afterwards was used by BenQ (old Simenens) for downloading of firmware, afterwards was used by Qisda (old BenQ). Now it was used In DVP (actually its name is: Siemens wp7).

In difference from other hardware makers, Siemens doent use jtag for factory restore, they are still playing with old UART/COM port tools.

as I wrote before +3,3v ,tx, rx, gnd are 1, 12,11,10 pins on Diagnostic port of DVP. Note: tx and rx can be switched viceversa due that tx on schematics is connecting to rx on connected device.

Workability of selfmade adaptor can be tested by circut of TX and RX together, while its connected to 3.3v and GND and COM port of PC with any COM port terminal program by loopbacktest.

Btw instead of playing good and bad Nokser, try do it with your owned dvp :), may be your luck is more this time.

About donations....Most of developers are working together, even if its their work they share with same kind of people for free. I dont want to count how much money I have spent for my bricked DVP's, tools for experiments, but its still fun to research without asking for it. If it will help I will spend money for good again!

I also agree with kid 100% - xda is de beste kennisschap voor pda en smartphones in de wereld.
[Venue Pro Windows Phone 7 Development] SirMcFrosty:
i agree with kid. and to clear it - i dont like to see that lil bit hope we got trough the experiments in this thread could be forced down trough bringing in some bad thoughts ;)

its a pitty that i cannot really help at this stage of development. but when it comes to ROM development and alpha/beta testing i am here to help out. may be my golden times as an alpha/beta tester are more from the good old windows mobile times. but for me it doesnt matter to trick around in WM or WP registrys and files as long its a stupid MS product ;)

btw i think its ok to donate to provide developer with the needed material. we all save at least a lot money and anger because we dont need to search/buy a new device for each new OS ;)
[Venue Pro Windows Phone 7 Development] Nokser:
luck? hehe practically, I paid for it device and I have no remorse. ;)

big thanks for your all efforts Mofotech!
[Venue Pro Windows Phone 7 Development] reker:
OMG...What happened?
[Venue Pro Windows Phone 7 Development] mofotech:
It's true. Nokser got taxed hard by customs in Poland when he received the phone. I don't know why that happened as I shipped it as a gift. It was close to 100 american dollars.

Anyways , I am tech savy also heineken78, I can try stuff out also but I need guidance. I have background in computers and I am pc techinican. Thats why when you started talking about com port, my mind clicked as the com port on a pc. I can also get a hold of another DVP to play around with for testing purpose. LOL, I don't want to mess with my DVP currently that is in good working condition. I am going to read over your replies again to understand more clearly and gather material in trying out the hack.

I am also watching this thread like a hawk. I just want to see... that we made it... we cracked the DVP. Thats why I sent a DVP to Nokser.

LOL, Hey Nokser ...don't give up that easy!
[Venue Pro Windows Phone 7 Development] SirMcFrosty:
Shhhht! :) don't ask! ;) just let them work quietly (and god damnit fast!) :D

---------- Post added at 09:34 AM ---------- Previous post was at 09:25 AM ----------

may be it's because you declared it as a gift. customs officers usually dont believe it and think its a trick to lower the tax which has to be paid so they will find out the producer price for a new device and on that u have to pay tax.

you have to give it yourself a price how much it is worth on the papers and make it look more used. may be then it would be less nokser had to pay. also stupid is nokser had to pay tax on the shipping costs too i think (its common).
[Venue Pro Windows Phone 7 Development] Nokser:
I had no choice. And this is Poland, and such is the duty of the United States.

Nowhere was described, it was a gift ...

And for me it's not a problem...
[Venue Pro Windows Phone 7 Development] mofotech:
umm...:rolleyes:

Well whats done is done! LOL, I actually got help from a friend who worked for Fedex. I got a high discount for shipping to Poland because of him. Anyways ....let's keep the ball rolling here. I smell victory.:victory:
[Venue Pro Windows Phone 7 Development] SmokinWaffle:
Looking forward to some progress, seems I found this thread at just the right time! :D

I'm here if it gets to the testing stage, will happily give it a go on my DVP.
[Venue Pro Windows Phone 7 Development] SirMcFrosty:
is it possible to give us a short and understandable update about the workprogress. may be one or more people can meanwhile help a bit when they have a nice overview about whats already solved and what needs to be solved and what tools can be used (also which solutions didnt work in total).

thx in advance
[Venue Pro Windows Phone 7 Development] mofotech:
I am in the process of acquiring a DVP from a friend. As soon as I get it... I can try things out as heineken78 iis saying to do. I don't know about Nokster, He may have given up. heineken78 has some detail and progress. We will try to work with that. I will also get into contact with dev who are in the middle east, perhaps brotherly love can help chim some noise for use and build some more progress. so let see where this takes us!
[Venue Pro Windows Phone 7 Development] Nokser:
I did not give up .. just do not put additional progress on this Section Forum.

@heineken78 it creates a solution unbrick device via j-tag.

I'm looking for another solution without j-tag, because when the machine stops the boot logo, it is not killed device ..

Both, the majority of Dell's user does not have the device type j-tag.

For them, we need create, simple solutions.

Nokser
[Venue Pro Windows Phone 7 Development] SirMcFrosty:
thx. and send him all our love - may be the progress will build up faster :)

keep us up-to-date ;)

---------- Post added at 02:43 AM ---------- Previous post was at 02:38 AM ----------

indeed. most of us dont have a jtag :( so its urgent to have a solution without when it shall be for a bigger userbase. from time to time an update will help to keep people interested and may be when more people respond other devs will see that it will make sense to still build something for DVPs ;)

btw thx nokser for trying
[Venue Pro Windows Phone 7 Development] mofotech:
I am getting a DVP tomorrow from my friend. I think its a bricked unit but it still powers on. I can use it for any testing purposes if needed. Let me know. Thxs Nokser.

Hey Nokser

Well , I got 2 dvp from my friend. BUT loll they both don't show anything on the screen when powered on! crap! lolll They power on and the keyboard lights up but nothing further then that. I don't know if I can somehow fix them. I may try to swap out the screens and see. See if unubtanium can be a tester.

-mofotech
[Venue Pro Windows Phone 7 Development] unubtanium:
I am willing to test almost anything to get WP7.8 on it.
[Venue Pro Windows Phone 7 Development] SirMcFrosty:
sry buddy only one well working dvp over here.

may i ask for what test/work do u need somebody with 1 working and 1 stucked dvp?
[Venue Pro Windows Phone 7 Development] unubtanium:
As you mention that the keyboard lights up, does it turn off after about 10-15 sec after turning on?

If NOT , the DVP do not load the os and you would not get anywhere (i think) with a screen change.

IF no one needs my faulty one, i can send it to u, if u want. The digitizer is cracked and the digitizer controller on the board are broken.(have tested with a working digitizer) BUT the screen itself is all fine and i can see that the os is loaded and so on....

So let me know, as this faulty phone is not doing me any good.

PS: no battery will be sent with it. :p
[Venue Pro Windows Phone 7 Development] SmokinWaffle:
I'm probably going to upgrade to the HTC8X next week which would leave me with a spare, fully working, DVP. I'm tempted to donate it to this project..
[Venue Pro Windows Phone 7 Development] mofotech:
Both DVP keyboard stay lite up and nothing comes on the screen. Actually one of them kinda has like a backlight lite up but doesn't display anything. I am going to recheck them again as I only briefly checked them.

If you bricked the phone, you can buy off eBay a new motherboard for the phone but the only bad thing is the seller is in the USA! Also its $40+whatever shipping maybe! I bought one of those motherboard and brought back one DVP to life. Try switching the microsd card out and redo a flash on to the phone to unbrick the phone? What do you think?

I have an unlocked DVP originating from Germany, latest firmware is still 7720 (since DELL gave up on us last summer).

The update was supposed to be released today at 6.00pm GMT.

It will be released in four waves, spanning three weeks from today. Just have a little more patience, if it comes to the venue pro, it'll come to all devices. (carrier branded devices may not get any).
